The key to successful rubber and plastics compounding is the accurate timing of activity – the property that regulates the rate at which magnesium oxide accepts by-products. Martin Marietta’s Elastomag magnesium oxide powders deliver the precise predictability needed in rubber manufacturing.

Manufactured to precise specifications in size, surface area, porosity and dispersion characteristics, Elastomag magnesium oxide products eliminate unnecessary cycle changes, reduce stock losses, and help maintain control over product consistency.

Consistent compounding times ensures accurate reproducibility with each production run.

Elastomag is available in the following formulations:
Elastomag 170 – A high activity, powdered magnesium oxide of uniformly small particle size.

Elastomag 170 Special – Similar to Elastomag 170 powder, but tested and assured to have a median particle size <3μ.

Elastomag 100 – A high activity magnesium oxide powder but with lower activity, surface area and LOI than standard Elastomag 170.
